[0025] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-5 As shown, the utility model provides a radio frequency front-end connection assembly, including a radio frequency front-end body 1, a plurality of ports 12 are fixedly arranged on the rear side of the radio frequency front-end body 1, a dustproof mechanism 6 is arranged on the rear side of the radio frequency front-end body 1, and the dustproof mechanism 6 includes a central tube 601 located on the rear side of the radio frequency front-end body 1;

[0027] The outer end of the central tube 601 is provided with a plurality of fixed sleeves 602 through a sealing bearing sleeve, and the bottom end of the fixed sleeve 602 is fixed with a hollow baffle 603, and the hollow baffle 603 corresponds to the port 12 one by one and is located directly behind the corresponding port 12;

[0028] The hollow baffle 603 is provided with a blowing hole 604 on one side facing the port 12 , which is communicated with the internal cavity of the hollow baffle 603 . The blowing hole 604 can blow air toward the corresponding port 12 . The fixed sleeve 602 is provided with two air holes 605 , which are opened at the outer end of the central tube 601 .

[0029] During the use of the RF front-end body 1, wind is generated by driving the air flow, thereby improving the heat dissipation efficiency of the RF front-end body 1. The wind after heat dissipation enters the interior of the central tube 601 from both ends of the central tube 601, and the wind entering the interior of the central tube 601 is blown outward to the interior of the fixed sleeve 602 through the air vents 605. The wind entering the interior of the fixed sleeve 602 then enters the cavity inside the hollow baffle 603. Finally, the wind is blown to the corresponding port 12 through the air blowing holes 604, which can effectively prevent dust from staying on the end. Port 12 can not only prevent dust from entering port 12, but also clean the original dust inside port 12, thereby improving the dust removal effect. When port 12 needs to be connected through a joint, the fixed sleeve 602 is rotated upward to lift up the hollow baffle 603 corresponding to the port 12 to remove the covering of the port 12, while other ports 12 are still blocked by the hollow baffle 603. Compared with the prior art, the dust removal of port 12 can be controlled individually instead of all ports 12 at the same time, which is more convenient and flexible.

[0030] The wind force for dust removal comes from the airflow during the heat dissipation process, such as Figure 1 , 5 As shown, both ends of the central tube 601 are fixed with end plates 5, and the end plates 5 are detachably arranged on the rear side of the RF front end body 1;

[0031] Both ends of the central tube 601 penetrate through two end plates 5 and are fixed with air guide hoses 8 .

[0032] Both sides of the RF front-end body 1 are provided with sealing covers 2 capable of dissipating heat for the RF front-end body 1, a partition 9 is fixedly provided on the inner wall of the sealing cover 2, and a plurality of exhaust fans 10 are inlaid on the partition 9, and one end of the air guide hose 8 is fixedly connected to the sealing cover 2 on the corresponding side;

[0033] The sealing cover 2 is fixed with fixing plates on both the front and rear sides. The fixing plates are connected to the outer shell of the RF front end body 1 by bolts, so that the sealing cover 2 can be easily installed and disassembled.

[0034] The sealing cover 2 is installed on the side of the outer shell of the RF front-end main body 1 through a fixing plate, and the exhaust fan 10 drives the air flow to guide the hot air generated inside the outer shell of the RF front-end main body 1 into the sealing cover 2, and then the air inside the sealing cover 2 enters the center tube 601 through the air guide hose 8, thereby generating wind force for dust removal. Wind force is used to remove dust while dissipating heat, thereby improving the utilization rate of wind force and reducing the cost of dust removal.

[0035] The exhaust fan 10 is used to drive the air flow to guide the hot air inside the RF front end body 1. Figure 1 , 2As shown in Figures 5 and 5 , a plurality of exhaust holes 11 for heat dissipation are provided on both sides of the shell of the RF front-end body 1 , and the positions of the exhaust holes 11 correspond one-to-one with the positions of the exhaust fans 10 , so that the exhaust fans 10 can discharge the hot air inside the RF front-end body 1 .

[0036] An inspection cover 3 is provided on the top of the housing of the RF front end body 1 by means of bolts, and a plurality of dustproof nets 4 are inlaid on the inspection cover 3 .

[0037] A power switch 7 is fixedly provided at the rear side of the RF front end body 1 to control the power on and off of the RF front end body 1. A plurality of pads are fixedly provided at the bottom end of the RF front end body 1 to raise the position of the RF front end body 1 and play a moisture-proof role.

[0038] Since the position of the exhaust fan 10 corresponds to the position of the exhaust hole 11, when the exhaust fan 10 is running, the hot air inside the RF front-end body 1 can be discharged through the exhaust hole 11. After the hot air inside the RF front-end body 1 is discharged, negative pressure is generated inside the RF front-end body 1, and the external cold air enters the RF front-end body 1 through the dust-proof net 4 after being filtered by the dust-proof net 4, thereby utilizing the flow circulation of air to dissipate heat for the components inside the RF front-end body 1.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
